And This step is mainly to clean the big impurities ,like the stone , big dust , iron etc .

2. Crushing Process: This Process is mainly to crush the peanut , as the peanut is big ,it is not easy to press .

We must crush the peanut to 6-8 pieces . Then we need to peel . The rate of peel is about 90% .

3. Flaking Process : After crush and peel ,we need to flake the crushed peanut , which make the cell wall of

peanut broken . And we flake the peanut to 0.55 mm thickness . Then it is useful for the oil extracting .

4. Cooking Process: After the flaker,we need to cook the flaked peanut , control the moisture at 5-7% ,

the temperature is 110-115degree .

5. Pre-pressing : After all the pretreatment , pre- press the peanut , the oil can be extracted about 76% .

2.Solvent extraction section :

After pre-pressing process , the requirement of peanut cake : moisture is about 8%, the residual oil :18-22%.

Use solvent organic solvent through soaking or spraying contact methods to extract oil from the cake. There is only less 1% oil content in meal after oil extraction machine .

Remark: The extraction workshop must be in a separate yard . This yard should be have at least 1.5 m

high brick wall all around ,the walls is 12 meters far from extraction workshop. Fire district : at least 30 meters far from residential area, keep from fire .

3.Groundnut/Peanut Oil Refining Machine

Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.

The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.

These processes include neutralization (removing free fatty acid), degumming, decolorization (bleaching), deodorization.Then you can get first grade groundnut/peanut oil .

4.Automatic Control System of Oil Solvent Extraction Machine

Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, extraction,

refining and fractionation in large oil plants. For its application in automatic control system, it can control the production in the entire

workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop, with efficient production management. It has reduced the production cost greatly and improved the management efficiency.
